As shown on the drawings:

The reference numeral I indicates a fountain pen barrel which is open atboth ends. Integrally formed on one end of the barrel I is a section 2,the outer end of which terminates in a threaded portion 3 on which aninteriorly threaded portion of a rfountain pen cap is adapted to bethreaded for holding the caprin position over the writing end of thefountain pen. For the pur-f pose of simplification, the fountain pen caphas been omitted. Projecting into the section 2 are a feed bar 4 and apen point 5. Engaged in the inner end of the feed bar 4 is an ink intakeand air tube 6 which projects axially through the ink chamber I of thefountain pen barrel to within 'a short distance of an annular shoulder 8which is formed on the interior of the barrel I a short distance fromthe outer end thereof.

Engaged in the end chamber 9 of the fountain pen barrel I is one form ofan improved filler unit comprising a stationary plunger or tube I0provided with an axial passage Il, the inner end of which continuesthrough a base plate or disc I2 which tightly seats against the shoulder8 of the fountain pen barrel I. The peripheral surface of the plate I2is in tight frictional sealing contact with the wall of the chamber 9 ofthe fountain pen barrel. Integrally formed on the outer end of thepassaged stem IIJ is a retaining head I3 which is centrally aperturedwith the aperture registering with the passage Il of the tube I0. Thetube I0, together with the plate I2 and the head I3 may be constructedof hard rubber or other suitable material.

slidably engaged over the stationary stem I0 and over the head I3 formedon the outer end thereof, is a filler device comprising a bulb orbellows I4 constructed of rubber or other suitable material and enclosedby a reinforcing or stiffening sleeve or covering I5 which may be glued,cemented, or otherwise secured around the exterior surface of thebellows or bulb I4. Secured in the inner end of the bulb I4 is acentrally passaged or apertured closure disc or bushing I6 constructedof hard rubber or other suitable material. The bushing I6 is slidablyengaged over the stationary stern I 0 and is adapted to contactthe innerface of the stem head I3 when the filling device is in its outermostposition, as illustrated in Figure 2, to limit the outward movement of.said filling device. The outer end of the bulb or rubber casing I 4 isclosed by means of a centrally apertured disc or bushing I1. Securedover the outer end of the bulb I4 and its cover I5 and'also enclosingthe gasket I'I, is a metalnishing cap I8. The filling device in itsnormal closed position projects into the end of the fountain pen barrelchamber 9 to close the end of the barrel. Rigidly secured to the cap I8and tothe bushing I1 is a button or knob I9 which is so formed that agroove 20 is provided between the head of the button I9 and the outerface of the cap I8 for the reception of the fingernails of a personshand when it is desired topull Vthe filling device out'- Wardly from thenormal position illustrated in Figure 1 into the fullV line position ofFigure 2. When the filling device is in the outermost positionillustrated in Figure 2, it is only necessary4 to project the feed bar 4and the pen point, 5 into a supply of ink and then manually, repeatedlycompress and release the bulb or rubber case I4 to cause ink to be drawnupwardly through the ink intake tube 6 to be deposited in the inkchamber 'I of the fountain pen barrel to fill the fountain pen.

Figures 4 and 5 illustrate a modified form of filling unit whichconsists of a stem unit constructed the same as the stem unitillustrated in Figures 1 and 2, and which is mounted to remainstationary within the chamber 9 of the fountain pen barrel I with thebase plate I2 seated against the shoulder 8. The filler device portionof the filling unit comprises a diametri- `cally compressible rubberbulb or casing 2| which is closed at its outer end by an integral top 22which is of diameter greater than the top end of the bulb 2|. Projectinginto the bottom surface of the projecting portion of the closure top 22are the upper ends of a plurality of metal strap springs 24 which extenddownwardly in spaced relation around the bulb ZI and have the lower endsthereof projecting into a base, 25 integrally formed on the lower end ofthe bulb 2|. Engaged around the bulb 2| and the strap springs 24 thereofis a metal mesh protecting covering or casing 26, the ends of whichengage around and are secured to the bulb top 22 and the base 25.Securely engaged over the outer end of the mesh covering 26 and the top22 of the bulb is a metal finishing closure cap 21 which normally isadapted to seat in the end of the chamber 9 of the barrel I to close thesame. Secured on the cap 21. is an operating button or knob 28, whichserves as a linger piece for moving the filling device from the positionillustrated in Figure 4 into an outwardly projecting position similar tothat illustrated in Figure 2 to permit alternate compression and releaseof the bulbous structure 2I within the protecting metal mesh housing 26.With the outward movement of the bulbous structure 2l and its covering,the stem unit I0 remains stationary Vwithin the barrel I with the stemhead I3 acting as a stop for limiting the outward movement of thebulbous filling mechanism.

`Figures 6, 7, and 8 illustrate still another modified form of fountainpen filling unit consisting of` a slidable filling device associatedwith a stationary stem mechanism secured within the fountain pen barrel.'Ihe parts which are simi-.

lar to those illustrated and described in connection with Figures 1 to 3inclusive are correspondingly numbered.

Slidably engaged in the barrel chamber 9 in telescoping relationshipwith the stationary stem III is a filling device comprising a bulb orbellows 29 constructed of soft rubber or other suitable material whichis closed at its upper or outer end by means of a cap or cover plate 30.Integrally formed on the lower or inner end of the bulb 29 is a passagedbase or bottom plate 3I- which .slidably engages overthe stem I0 withthe stem head I3 positioned inside of the bulb 29. Secured over the bulb29 is a metal protecting casing. 32 having finger openings orl windows.33 provided in op-posite sides thereof to permit access to be had to thesides of the bulbous structure for compressing the `same for filling.the fountain pen. The` upper end of the protecting casing 32 is closedand has secured or formed thereon a inner end of the protecting casingl32 is open'and engages around the base 3l of the bulb 29.

Figures 9, 10, and 11 illustrate another modified form of fountain penfilling unit in which the stem mechanism is omitted and wherein theouter end of the recess or chamber 9 of the fountain pen barrel l has ametal stop sleeve 35 secured therein for limiting the outward movementof the fountain pen filling unit, which normally is seated against thestop shoulder 8 in the barrel l, as illustrated in Figure 9.

'I'he filler unit comprises a metal tube or casing 36, provided withdiametrically opposite longitudinally disposed openings or slots 31. Theouter end of the casing 36 is closed by means of a top plate or plug 38having a button or knob 39 formed on the outer side thereof. The innerend of the casing 36 is closed by means of a base `plug 40 having anaxial passageV 4l provided therethrough. The base plug 40 is providedwith a shoulder at 42 whichis adapted to seat against the end of thestop sleeve 35 to limit the outward movement of vthe filler unit whenthe same is moved into an operating position, as illustrated in Figure10. The inner end of the base plug 40 is circumferentially grooved toprovide a shank portion 43 around which the open end of a filling bulbor bellows 44 is secured. The bulb 44 projects upwardly into the casing36 between a pair of oppositely positioned actuating bars or plates 45disposed within the casing 36. Each of the plates 45 is provided with afinger piece or ear 46 which projects outwardly through one of the slots31 in the casing 36. The bulb 44,which is constructed of rubber or othersuitable material, normally acts on the plates 45 to project the fingerpieces 4B outwardly through the slots 31 into an actuating position,when the filling device is pulled into its outermost operating positionas shown in Figure 10. When the filling device is projected into thechamber 9, as shown in Figure 9, the projecting finger pieces 46cominginto contact with the stop sleeve or collar 35 are projected intothe sleeve or casing 36 thereby causing'the actuating plates 45 tocompress the bulb 44 when the filler device is not in use. y

To fill the fountain pen, it is only necessary to engage the knob 39topull the casing 36 from` the position illustrated in Figure 9 into theprojecting position shown in Figure 10, in which position the resilientbulb 44 acts to project the actuating finger pieces or ears 46 outwardlythrough the slots 31, so that when the finger pieces 46 are compressedand released, the filler bulb 44 is compressed and released therebycausing ink to be drawn upwardly through the ink intake tube 6 to fillthe fountain pen.

It will, of course, be understood that numerous details of constructionmay be varied through a wide range without departing from` theprinciples of this invention, and it is, therefore, not the purpose tolimit the patent granted hereon otherwise than necessitated by the scopeof the appended claims.
